| dc.description.abstract | A search for pair production of second-generation scalar leptoquarks in the final state with two muons and two jets is performed using proton-proton collision data at ?s=7??TeV collected by the CMS detector at the LHC. The data sample used corresponds to an integrated luminosity of 34??pb?1. The number of observed events is in good agreement with the predictions from the standard model processes. An upper limit is set on the second-generation leptoquark cross section times ?2 as a function of the leptoquark mass, and leptoquarks with masses below 394 GeV are excluded at a 95% confidence level for ?=1, where ? is the leptoquark branching fraction into a muon and a quark. These limits are the most stringent to date. | es_ES |
| dc.description.sponsorship | We extend our thanks to Michael Krämer for providing the tools for calculation of the leptoquark theoretical cross section and PDF uncertainty. We wish to congratulate our colleagues in the CERN accelerator departments for the
excellent performance of the LHC machine.
